The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that the removal of keystone species causes serious disruption in the functioning of the community. - Keystone species are those that have a disproportionately large effect on their environment relative to their abundance. 2. **Understanding the Reason**: - The reason states that keystone species drive major ecosystem functions. - This means that these species play critical roles in maintaining the structure and health of the ecosystem. 3. **Connecting the Assertion and Reason**: - If keystone species are responsible for vital ecosystem functions, their removal would lead to a breakdown in these functions. - For example, if a top predator (like a lion or tiger) is removed, the population of herbivores may explode, leading to overgrazing and a decline in plant life, which can disrupt the entire ecosystem. 4. **Conclusion**: - Both the assertion and the reason are true. The assertion is correct because the removal of a keystone species indeed causes serious disruption in the community. The reason is also correct as it explains why the assertion is true; keystone species drive essential ecosystem functions. 5. **Final Answer**: - Therefore, the correct answer is that both the assertion and the reason are true, and the reason correctly explains the assertion.
